I had lower abdominal pain/ache (the left side) for two weeks before my last menstrual cycle (it was on the 23rd of May). It was gone for a while when my period came. Since the 6th of June, I've had lower abdominal pain again; but this time I found it hard to identify an actual pain area. The pain (not serious) was most obvious when I urinate as I felt the pressure on my abdominal. This evening when I pee, I had mild burning feeling.

Last month I started peeing all the time (a few times within 30 minutes. the flow was medium). So I started drinking cranberry juice and it seemed to ease the situation.

I wonder if I have contracted bladder infection. The last time I had bladder infection was 2006 Jan. But that time when I pee it was extremely painful. Not like this time I just felt the "pressure" and "sore".
